Applications
Meat, Broth and Savory Flavor Compounds
Methionol contributes the meaty and soup-like portion of savory flavor compositions. Typical formulation directions include broth flavors, meat seasonings and savory sauce flavors. Its onion and garlic nuances can form part of the cooked-food character within the blend.
The ingredient is used for its aroma contribution in a compound flavor. The finished profile reflects its concentration alongside the other aroma ingredients. For food flavor manufacture, suitability applies to the actual supplied grade and intended market.
Soy Sauce and Fermented Seasoning Flavors
The soy-associated note makes methionol relevant to soy sauce and fermented seasoning flavor compositions. Its savory, vegetable and sulfur nuances form part of the aroma profile in these blends.
Its role is the savory aroma component in the flavor concentrate. The soy-associated note sits alongside its potato, vegetable and garlic nuances.
Sulfurous Fragrance Compositions
Methionol offers a sulfurous accent for specialty fragrance accords, including onion and garlic nuances. The International Fragrance Association's Fragrance Ingredient Glossary records these odor descriptors. In this application, the material serves as a focused olfactory accent within a compound fragrance.
Solubility and Formulation
The liquid form suits incorporation into liquid aroma concentrates. Alcohol, propylene glycol and oils are relevant solvent or carrier options. The carrier must be compatible with the rest of the concentrate and suitable for its end use.
The powerful aroma calls for controlled addition in concentrated flavors. The desired meaty, broth-like or sulfurous contribution is assessed at the finished-use dilution, where the balance of the aroma ingredients becomes apparent.
